Tyronne, I would say no. Better to drill them out one at a time and replace them as you go. They need to be hot rivetted, and two hands make the job easier, one to man the torch doing the heating, and the other to position the drum and do the setting.

Those are cold riveted. No reason to heat the rivets. You may affect the temper by heating the rivets. I have riveted many of these cold. After riveting you will need to chuck up in the lathe and face off the buck tails of the rivets.
